Ecological justice is cultivated by an ethics of truth: it is nourished by concerned address and attuned response, and it grows over time in and through the attempt to put things into their proper words. The ethics of truth is rooted in a twofold responsibility that conditions the way human-beings in-habit the world. At the surface, this twofold responsibility announces itself in our rudimentary encounters with perceptible things; from the depths, it is heard in our attempts to articulate the intelligibility of things. At the surface, responsibility is twofold insofar as our encounters in perceiving at once lend themselves to our perceptive abilities to respond and awaken us to an insistent unicity that enjoins response even as it remains recalcitrant to human articulation. From the depths, responsibility is twofold insofar as our abilities to respond intelligibly to the coherent integrity of things awaken us to the expression of the whole that presses upon us an obligation to speak in light of the good and the beautiful, however dimly discerned. The human ability to respond thus opens human-being to responsibility from two directions.
